Abstract

We show that, owing to a decrease in the dipolar energy, the soft cores of the nonsingular, doubly quantized vortices in ³HeA₂ expand and become ellipsoidal upon approaching the A1 phase. Results of zero sound experiments in rotating ³HeA₂, very near the A₂A₁ transition, support this conclusion. The experimental data was analyzed by a geometrical acoustics method, using theoretically calculated attenuation and velocity parameters.
